What it is

Practical, non-regulated finance help for small businesses: budgets, cash flow forecasts, pricing checks, management reports and business plans for loan or grant applications.

Your first three steps

  1. Pick a niche, such as trades, hospitality or start-ups, and write a simple one-page service list with prices
  2. Set up as a sole trader with HMRC and get a quote for professional indemnity and public liability insurance
  3. Offer a discounted cash flow review to three local businesses and ask for a written testimonial
Who pays

Sole traders, small limited companies, start-ups and community groups that don't have a finance director.

How it makes money

Day or hourly rate, fixed fees for projects such as a forecast or funding pack, or a monthly retainer for regular reviews.
